MINER/S LAMP.

Specification of Letters Patent.

Patented May 14, 1912.

Application filed August 26, 1911. Serial No. 646,268.

To all whom it may concern Be it known that I, NELSON BLoUN'r, a citizenof the United States of America, re siding .in the borough of Manhattan,in the city, county, and State of New York, have invented certain newand useful Improvements in Miners Lamps, whereof the fol lowing is aspecification.

This invention is especially applicable to miners lamps used in metalmines where safety lamps are not required.

The object of the invention is to provide a lamp with supporting meanshaving a variety of adjustments for holding the lamp in verticalposition whether upon the wall, ceiling, post, shelf or any part of themine.

Figure 1 of the accompanying drawings represents a side elevation of amine lamp provided with supporting means embodying the preferred form ofthis invention. Fig. 2 represents a rear elevation thereof, showing infull lines one position of the hook handle, constituting a part of thesupporting means and indicating in dotlines and in dash-dot lines twodifferent positions thereof. Fig. 3 represents a horizontal section online 33 of Fig. 1 of the supporting means and a section of a fragment ofthe lamp body to which said means are secured.

The same reference numbers indicate corresponding parts in the differentfigures, round numbers being used to designate the principal elementsand intermediate numbers for the subordinate features thereof.

A mine lamp 10, which may be of the acetylene or other type, is providedwith a supporting means which has a variety of adjustments. In the formshown this means comprises a fixed bracket 20 secured to the body of thelamp by rivets passing therethrough and through the attaching straps 21and 22 of said bracket. The bracketis preferably rectangular in form andprovided with an outer flat bearing face 25 and with a stud hole or bolthole 24. This bracket forms a pocket 25 between it and the lamp body. Apivot stud 30 is secured to said bracket. This piyot stud may be of anysuitable construction. As shown it consists of a bolt passed through thebolt hole 24 and having a head 31 at its inner end within the pocket 25and a wing nut 35 at its outer end.

A swiveling clamp 40 is disposed on the stud 30 and held against thebearing face 23 of the bracket 20 by the nut 35. This clamp consists ofa folded metallic str'ip comprising jaws 41 and 42 and an open socket 43at the closed end thereof. A hook handle 50 is held in the socket 43 ofthe clamp 40 by means of the wing nut 35 and is adjustable in saidsocket by the same means. This hook handle consists of a straight shank51 having a sharpened prong 52 at its lower end integral with or infixed relation to said shank and a hook 53 at its upper end. The shortleg of this book 53 is provided with a sharpened prong 54, which ispreferably bent outwardly from the shank 51 as shown in Fig. 1 and alsolaterally with reference to said shank as shown in Fig. 2. The hookhandle has a longitudinal or sliding adjustment in the jaws of theclamp, also a rotary adjustment therein, and owing to the swiveling ofthe clamp the hook handle may be adjusted at various inclines relativelyto the lamp. The book handle is locked in or released from any of itspositions of adjustment by means of the clamp and ring nut.

In the use of this invention, the lamp is carried by grasping the hookhandle which is normally in the position in which it is shown in Fig. 1.For supporting the lamp in vertical position from the sidewall of themine, the hook handle may be swung into right angular position indicatedby dot lines in Fig. 2 and the jabbing prong 52 forced into saidsidewall. When it is desired to depend the lamp in vertical positionfrom the ceiling of the mine the hook handle 50 is reversed so that thesharpened prong 52 projects directly upward as shown in clotdash linesin Fig. 2 and "the hook is then driven into the ceiling. If the wall orceiling to which the hook handle is to be driven be inclined, said hookhandle may be swung to any desired angle to accommodate it to suchinclined surface while maintaining an uprightposition of the lamp. Incase the lamp is to be secured to an upright timber of the mine frame,the bent prong 54 of the hook 53 may be readily pressed or driven intosuch timber; likewise if the lamp is to be supported from a horizontalor inclined timber, the prong 54 may be pressed or driven thereinto. Incase the lamp is to stand on a surface subject to movement or vibration,the clamp is loosened and the shank of the hook handle is adjustedlongitudinally so that the straight prong thereof projects below thebottom of the lamp, where it will penetrate such surface and hold thelamp in upright position.

I claim as my invention:

1. The combination of a lamp, a hook handle therefor provided with asharpened prong in fixed relation thereto, and a con necting meansbetween said lamp and hook handle which permits a plurality of differentadjustments of the one relatively to the other.

2. The combination of a lamp, a hook handle therefor provided with asharpened prong in fixed relation thereto, and connecting means whichpermits longitudinal, rotary and inclined adjustments of said hookhandle with relation to said lamp.

8. The combination of a lamp, a hook handle therefor provided with asharpened fixed prong, and a clamp engaging said hook handle and havinga swiveling adjustment in connection with said lamp.

l. The combination of a lamp, a hook handle therefor comprising a shankprovidedat one end withasharpened prong and at the other end with ahook, both in fixed relation to said shank, and a connectingfixedrelation to said shank, and a connecting means which permits the axialadjustment bodily of said hook handle relatively to said lamp.

6. The combination of a lamp, a hook handle support attached thereto,and a hook handle axially adjustable bodily in said support and providedwith a sharpened prong.

7. The combination of a lamp, a hook handle therefor comprising a shankprovided at one end with a sharpened prong and at the other end with ahook having a laterally bent sharpened prong, and a connecting meanswhich permits the adjustment of said hook handle relatively to saidlamp.

8. The combination of a lamp, a hook handle therefor provided with asharpened prong in fixed relation thereto, and a connection which Iermits the axial adjustment bodily of saicF handle relatively to saidlamp.

9. The combination of a lamp provided with a bracket having an outwardbearing face and an outwardly projecting pivot stud, a clamp swiveled onsaid stud, a hook handle adjustable in said clamp and provided with asharpened prong, and means on said stud for tightening and releasingsaid clamp. 1
